| Abstract: | The plate tectonic setting and genetic types of the gas (oil)-bearing basins in China are studied. Based on the history of
break-up and amalgamation of Pangea, the three tectonic evolutionary megastages can be divided and the sedimentary basins
in China are classified as Palaeowic and Meso-Cenozoic basins. The Palaeozoic gas (oil) bearing basins are mainly located
in intracratonic basins, on which different types of Meso-Cenozoic basins are superimposed, and located in cratonic marginal
basins and aulacogens destroyed with a slight degree. In contrast, the Mesozoic and Cenozoic gas (oil)-bearing basins mainly
formed in extensional foreland and intracontinental shortening flexural basins. |
